Thinking Inside a Bigger Box

I have been looking for a while for a refactoring tool that could improve the encapsulation of my code. More specifically, I want to be able to analyse a closure of code (like what JDepend does), and make methods private, package protected or protected as much as possible.

Of course, if it is to be useful, there has to be a good way of defining root classes and methods, ignored name patterns (getters/setters for those who are still addicted to those) etc.

If anyone reading this has seen such a tool, please let me know. Otherwise, I am considering writing one using something like RECODER. But there is a bit of a stiff learning curve ahead…
